DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 436,197, dated September 9, 1890.

Application led April 25, 1890. Serial No. 349,424. (No model.) A

vnals.

The objects of my invention are to provide strong and durable rider-bars which will securely confine the roller, and which can be constructed at comparatively small expense, and to provide simple means for removing the roller from the rider-bars when desired.

In the accompanying drawings, Figure lis a side elevation of my improved door-hanger.

Fig. 2 is an end elevation of the hanger, showing the door and rail in section. Fig. 3 is a vertical section inline Fig. l. Fig 4 is a top plan view ofthe hanger. Fig. 5 is a longitudinal section of the same. Fig. 6 is a horizontal section in line y y, Fig. l, looking upward. Fig. 7 is a cross-section of one of the rider-bars, on an enlarged scale.

Like letters of reference refer to like parts in the several figures.

A represents the door, and B the overhead beam provided with a rail b, on which the hanger runs.

O represents the horseshoe-shaped frame of the door-hanger secured', with its curved lower portion to the door, and having its ends c extending upwardly on one side of the beam and rail and curved over the latter and projecting downwardly at the rear side of the hanger, as represented at c.

D D represent two horizontal rider-bars secured, respectively, to the upwardly-extending front portions c and the downwardly-projecting rear ends c of the frame. These rider-bars are straight channel-bars, preferbly formed of rolled steel, and arranged with their channeled r grooved sides inwardly or toward each ot er. The upper ange d of each rider-bar is made horizontal on its lower side, so as to stand at right angles to the inner side of the channel-bar, and beveled on pose of permitting the bars to be rolled, and

the lower flanges d are beveled for the same purpose.

The top and bottom flanges 4are ont awayv at both ends of each rider-bar to permit the frame to rest against the webs of the bars, as represented in Fig. 5.

The lower flanges d of the rider-bars are provided, preferably at both ends, with longitudinal slits f, extending inwardly from the ends of each fiange, as represented in Fig. 6, a sufficient distance to permit the lips g so formed to be bent down, as represented in dotted lines in Fig. 5.

- Vhen it is desired to remove the roller from the hanger for renewing the roller or shaft or for any other purpose, the two lips at one end of the hanger are bent down sufficiently to permit the roller to be removed, and when the roller has been replaced they are bent back to a horizontal position to confine the roller between the rider-bars.

rlhese rider-bars are very strong, light, and durable, and can be easily secured to the hanger-frame, constituting therewith a light and rigid frame.

l claim. as my inventonl. The combination, with the roller and the hanger-frame, of rider-bars provided with a releasing-lip which can be bent out of its normal position to permit the vroller to be withdraw-n, substantially as set forth.

2. The combination, with the roller and the hanger-frame, of channeled rider-bars having their lower flanges provided with end slits forming releasing-lips, substantially as set forth.

Witness my hand this 4th day ot' April, 1890.
